.45-70 Government is a rifle cartridge designed for military use that found widespread adoption among sporting enthusiasts in the 20th century. It enjoys renewed popularity among hunters and special forces operators in the post-nuclear world.
Also known as the .45-70 Government, this cartridge was originally created at the U.S. Army's Springfield Armory. Intended for use in the Springfield Model 1873 breech-loading rifle, it was a replacement for the stop-gap .50-70 Government cartridge adopted in 1866. A powerful rifle round that eventually fell out of use due to the general shift towards standardized .30 caliber ammunition in the late 19th century, the .45-70 enjoyed popularity among hunters who appreciated it ballistic performance and firepower. Used for hunting big game throughout the 20th and 21st centuries, it became a highly sought-after ammunition type in the wake of the Great War. Used across the United States by big game hunters who once more appreciated its performance against mutated wildlife, the cartridge was also adopted by the NCR Rangers and other military outfits to hunt the most dangerous game in the wasteland: Man. As a result, the .45-70 cartridge remains in use across North America, from Baja California to Far Harbor Maine.
